GAN SQLDERlNG HViPLEWlENTH Specification of Letters Patent.

Patented Feb. 12, 1907.

Application filed February 2, 1906. $erial 1\T0.299,185.

To (tZZ 1072 0721 it nuty concern.- I Be it known that I, SAMUEL A. V ARNEY, a l citizen of the United States, and a resident l of "ashington, in the county of Washington l and State of Kansas, have invented certain l new and useful Improvements in Can-Soldering Implements, of which the following is a specification. 1'

My invention relates to devices for holding I the bodies of cans or similar sheet-metal vessels while they are being soldered or otherwise worked upon.

More particularly described, it consists in l a convenient hand-tool having an expanding l mandrel adapted to grip the can. I

It is of economical construction and adapted to perform its work in an eflicient manner.

Other advantages of my invention will appear hereinafter in connection with a detailed description thereof, reference being had to I the accompanying drawings, which illustrate an exemplification of the invention, J and in which Figure 1 is a perspective view of the implement with the mandrel expanded, and Fig. 2 l is a detail view showing the mandrel closed.

1 is a shaft composed conveniently of elbow-shapcd angle-pieces 2, four of which are placed together and secured in any suitable manner.

3 is a handle, conveniently of wood, at the top of the shaft; 4, upper links, having their 1 inner ends inserted between adjacent flanges of the elbow-strips 2 and pivotally secured by rivets at 5; 6, connectin -strips, preferably of bent sheet metal, pivoted at 7 to the outer ends of arms 4; 8, lower links similarly pivoted to the shaft and to the connecting-strips 6; 10, curved plates, one secured to each of the connecting-strips 6 and adapted to en gage the inner surface of the can-body.

Four plates and four corresponding sets of I links are shown in this instance, and the I shaft is formed so as to correspond to this number of plates; but it is apparent that the number of plates and corresponding parts i and the shape of the shaft may be varied as desired.

The upper links 4 are made somewhat longer than the links 8, and their pivot-points 5 are set on the shaft so that when the mandrel is expanded, as in Fig. 1, the links not parallel, the upper links inclining slightly upward toward the center. This construction makes the outer surfaces of the plates parallel in expanded position.

As shown in Fig. 2, when the plates are collapsed the arrangement and proportion of the links cause the tops of the plates to fold close to the shaft, while the lower ends are somewhat expanded. This convergence of the plates toward the top renders it very much easier to remove the can than in a structure in which the plates are in the same relative position when expanded and collapsed; but it is apparent that many features of my invention are adaptable to either form of construction.

The operation of the device is very simple and will be apparent to those versed in the art. In placing the mandrel in a can-body it is first collapsed, then inserted in the body, and downward pressure against the bottom of the can or against any fixed rest forces the shaft downward and the toggles outward and brings the plates into contact with the can body with a very firm pressure. To remove the device, the can is held and the handle pulled outward, which causes the mandrel to collapse, and it may then be easily Withdrawn from the can, especially when the conical form is used.

M any changes in detail are possible without departing from the spirit of my invention.

W hat I claim is 1. In a can-holding implement, the combibination of a shaft, a handle thereon, a plurality of curved plates, a link connecting each plate with the shaft at one end, another link connectin each plate with the shaft at the other end, the links at the opposite ends of l the plates being of different lengths so that when the plates are collapsed the ends nearest the handle are drawn closer to the shaft than the other ends.

2. In a can-holding implement, the combinaticn of a shaft, a handle thereon, a plurality of curved plates, a link pivoted to the lower end of each plate and to the corresponding end of the shaft, and another link pivoted to the upper end of each plate and to the shaft at an adjacent point, the upper links being longer than the others and so arranged that when the plates are collapsed toward the shaft the upper ends of said plates are nearer the shaft than the lower ends.

In testimony whereof I have affixed my signature in the presence of two witnesses.
